Then we conduct compression processing on color image based on four-dimensional (4-D) vector DCT orthogonal transform. Simulation results demonstrate that the proposed modes provide better compression performance than JPEG.关键词: scan mode multi-dimensional vector matrix discrete cosine transform (DCT)...

Characterizing the behavior of a chaotic, multi-dimensional system is achieved by measuring each of a number of signals associated with the system, and generating therefrom, a spatio-temporal response based on each signal. Chaoticity profiles are then generated for each spatio-temporal response. Ove...
In process of automatic parallelizing/vectorizing constant-bound loops with multi-dimensional arrays under specific dependence direction, the Lambda test is claimed to be an efficient and precise data dependence analysis method that can check whether there exist generally inexact `real-valued' solutions...
nda is a C++ library providing an efficient and flexible multi-dimensional array class. It is an essential building-block of the TRIQS project. Some features includecoded in C++17/20 using concepts expressions are implemented lazily for maximum performance flexible and lightweight view-types matrix ...
{\mathcal{B}}}[\cdot ]\) describe the initial and boundary conditions (I/BCs) of the system, respectively; \({{{\boldsymbol{\lambda }}}\in {{\mathbb{R}}}^{d}\) is a d-dimensional vector, representing physical/modeling parameters in the governing PDEs and/or I/BCs. Solving this...
dimensional state, followed by a tailoring step to convert it into specific desirable classes, here the GHZ states are generated as an example. Finally, the states are directed to two measurement devices: the vectorial nature of the prepared states is measured by a polarizer and camera (OAM-...
Arrays and vector operations All of Upsurge's linear (1-dimensional) operations can be performed on anything that conforms toLinearType. Swift's built-in arrays and array slices conform toLinearType, of course. But Upsurge also defines theValueArrayclass to store a one-dimensional collection of...
Stokes vector maps: (a) Fused; (b) S1; (c) S2. Figure 13. Polarization feature parameter maps: (a) DoLP; (b) AoP. This paper adopts four quantitative indicators widely used in the field of spectral–polarization image visualization, namely 𝜇μ, 𝜎σ, EN, and AG, to measure ...
